The measure of anglerst can be represented by the expression (6x 12)°. three lines extend from point s. the space between lines

miv72 [106K]

Answer:

∠RST = 120°

Step-by-step explanation:

We assume the positions of the lines and angles will match the attached figure. The angle addition theorem gives a relation that can be solved for x, then for the value of angle RST.

∠RSU +∠UST = ∠RST

78° + (3x -12)° = (6x +12)° . . . . . substitute given values into the above

54 = 3x . . . . . . . . . . . . . . . . divide by °, subtract 3x+12

108 = 6x . . . . . . . . . . . multiply by 2

120° = (6x +12)° = ∠RST . . . . add 12, show units

The measure of angle RST is 120 degrees.

<em>Additional comment</em>

Note that we don't actually need to know the value of x (18) in this problem. We only need to know the value of 6x.

A bowl contains 8 chips: 4 blue and 4 red. Three chips are drawn at random and without replacement from a bowl. What is the prob

PIT_PIT [208]

Answer:

the probability that 3 blue chips ( or red chips) are chosen is P(X=3) = 1/14

Step-by-step explanation:

Since the X= choosing x blue chips, then P(X) follows an hypergeometric distribution , when sampling is done without replacement

P(X=x) = (C,x) * (N-C , n-x) /( N ,n)

where ( ) represents combinations then

N= population size = 8 chips

n = sample size = 3 chips

C = number of blue chips = 4 chips

x= number of blue chips that are chosen = 3 blue chips

replacing values

P(X=3) = (4,3) * (8-4 , 3-3) /( 8 ,3) = (4,3) * (4 , 0 ) /( 8 ,3) = 4 * 1 / [ 8!/(3!*5!) ] =

4*3!*5! /8! = 1/14

P(X=3) = 1/14
